Formerly included in a broad Sylviidae. Recent review#R indicates that previous internal arrangement, with all taxa of present family split between Seicercus and Phylloscopus, was paraphyletic. As a result some authors have split Phylloscopus into several smaller genera, with some movement of taxa from Phylloscopus to Seicercus, but accuracy of this debatable on present knowledge. One of these versions#R involves groups containing species as listed below: Rhadina (species 1–3); Abrornis (species 4–13); Phylloscopus (species 14–28); and Seicercus (species 29–78). Another version#R divides family into nine genera. More cautious alternative involves merging Seicercus into Phylloscopus; adopted herein, pending results of a comprehensive study currently in progress#R.
